Spray on coating- stop rust in seams, doors, sills, et

[nvrstuk]

I asked about this months ago and lost the thread! Here or fb. Well I'm ready now!

There are sprays you can use inside doors, seams, etc that puts a coating (like a wax) on the metal (not paint) that helps keep it from rusting...

What have you guys used?

 

[hyghlndr]

Fluidfilm ?

Sounds right??? Some of it is like a thin wax...

Fluidfilm ?

i also plan to soak the inside bottom of doors with fluid film and in the rockers.

Product commonly known as Cavity Wax.
You will find Many manufacturers like FluidFilm, 3M, KBS, etc.

IIRC fluid film is basically lanolin and some other ingredients. there used to be recipes online for making it yourself much cheaper than buying them

I use this stuff at work and at home. https://www.theruststore.com/Valugard-Automotive-Cavity-Wax-Aerosol-P393.aspx

I use linseed oil on my gmc, keeps it nice and sealed up. Also use it on gates to seal the metal before painting. Works really good

I use beeswax on some of my metal tools that I don't want to paint. Get the surface too hot to touch but not so hot that it burns the wax, rub a stick of beeswax on it, and wipe the excess off with a rag before it completely cools down. Leaves a nice finish and I bet it lasts longer than fluidfilm.

You need to apply fluidfilm yearly to keep it effective, but it also works very well and your Bronco will smell like a sheep for a few days after application.

I think Cosmoline is common in the military, but I haven't used it before.

Found this on Cosmoline - seems like a hot ticket:

I don’t plan on driving mine in salt, but for all of you that live in the rust belt and try to keep whatever your daily is nice, the lady at my parts store said there’s a new product coming out that neutralizes salt. You spray it on before you wash I guess? I can’t remember what it’s called it sounded interesting....

You can paint over linseed oil?

Yes with normal oil base enamels. not sure about automotive paint, the solvents are much stronger.

Here's some instructions on using linseed oil as a sealant. They cut it 3:1 with mineral spirits to help it dry, I just put it on straight and let it sit for a week and then paint it.

Cosmoline is pretty serious stuff...we used to hose down big industrial equipment with bare steel shafts and such with the stuff to keep it from rusting when sitting on the deck of a freighter for months sailing around the oceans to whatever country they were intended. Getting it off is a whole 'nuther story...grab a bug mask and a bunch of MEK and go to town.

I use Fluid Film also. A bit messy to use, but it offers good rust protection.

If the part is small enough, You remove Cosmoline with a bath of boiling hot water.
That's how it is done for stored M-1 Garand parts...
